It takes advantage of the impact energy to crush the materials. The rotor is rotated to high velocity under the impeller by the electric motor, Materials from the feed inlet are collided with the plate hammer on the rotor, the material is crushed by the high-speed impact of the plate hammer. the crushed materials will be counter-back to the lining plate where they will be crushed again, finally will be discharged from the outlet.
